[Bug 1086459] Re: Name resolution over VPN fails; mdns4_minimal returns NOTFOUND
@charleshb: This isn't the same bug as #1086459 which involves mdns returning NOTFOUND before dns is tried. Whereas you already have dns before mdns on the hosts line in your /etc/nsswitch.conf. You may be suffering from bug #1003842. Please comment out dns=dnsmasq in /etc/NetworkManager/NetworkManager.conf and then do: sudo stop network-manager sudo killall dnsmasq sudo start network-manager and see if this fixes the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1086459 Title: Name resolution over VPN fails; mdns4_minimal returns NOTFOUND To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nss-mdns/+bug/1086459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1086459] Re: Name resolution over VPN fails; mdns4_minimal returns NOTFOUND
I'm suffering from the same bug. First nslookup is w/o VPN, name resolution works just fine. Once I'm connected to vpn clemson.edu names resolve but other domains do not resolve. I did a second set of nslookups at the end of this to show the last.

[Bug 1086459] Re: Name resolution over VPN fails; mdns4_minimal returns NOTFOUND
I'm having the same problem that DNS resolution stops working after a VPN connection (Cisco VPN) is established. However changing /etc/nsswitch.conf like in comment #20 does NOT work for me. I still get *unknown host* messages from ping.

[Bug 1086459] Re: Name resolution over VPN fails; mdns4_minimal returns NOTFOUND
This is likely unrelated, but any traffic sent over the VPN connection sputters and dies after about 5-10 seconds. For the initial 5-10 seconds, Internet and local names resolve without issue. After this, all name resolving traffic fails, and the VPN eventually gives a VPN Connection Failed message after about one minute.

[Bug 1086459] Re: Name resolution over VPN fails; mdns4_minimal returns NOTFOUND
Here's a more up-to-date link than the one I gave in comment #22. https://help.ubuntu.com/12.10/serverguide/network-configuration.html The relevant passage hasn't changed: it still says if you prefer to use legacy Unicast DNS versus Multicast DNS, you can change the string in /etc/nsswitch.conf as shown below. hosts: files dns [NOTFOUND=return] mdns4_minimal mdns4 But based on my incomplete understanding of nss-mdns I would think that in this sequence mdns4_minimal is redundant. This should be equivalent but faster: hosts: files dns [NOTFOUND=return] mdns4 Please let me know if I'm overlooking something. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1086459 Title: Name resolution over VPN fails; mdns4_minimal returns NOTFOUND To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/1086459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
